there is a noise like some kind of pump running seems to be coming from under trunk or in gas tank? rns for about 3 min any ideas?
when starting car sometimes a noise from the back end (under trunk, gas tank) sounds
like a air compressor running or some kind of pump what could this be?
Air pump for the cars ai rride suspension.
Where is the pump located? Thanks again
Passenger side rear above the muffler, it is an air compressor. As long as it stops running in a few minutes it's normal. If you find out running non stop, rust has decayed the integrity of the unit and it's a $500 min replacement.
